To aZZ whom t may concern:

Be it known that I, VILL H. VAN GUIL- DER, a citizen of the United States, and resident ofA New Rochelle, in the county of lVestchester and State of New York, have invented certain new and useful Improvements in Molding-Machines, of which the following is a specification.

TheA present invention relates to molding machines and more particularly to the type employed for building concrete walls in situ, an obj`ect of this invention being to provide a construction which has a maXimum adjustability in order that it may be used in the greatest variety of places with the fewest number' of parts.

To this and other ends, the invention con' sists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings l f Figure 1 is an end view of a. machine constructed in accordance with the present invention;

Figs. 2 and 3 are sections, respectively, on the lines o o and -b of Fig. 1;

Fig. 4 is a plan view of two machines connected for forming a corner;

Fig. 5 is a view in elevation of the two machines shown in Fig. 4;

Fig. 6 is a plan view of three machines connected together to Jform two corners and, in addition, to form a wall in close proximity to a window frame;

Fig. 7 is a. detailed view of one of the clamps for securing' a mold wall to its frame;

Fig. 8 is a chine formed from two straight wall work;

Fig. 9 is a sectional View showing the manner in which the core of Fig. 8 connects with the two frames; and

Fig. 10 is a perspective view of the core shown in Fig. 8.

Fig. 11 is a perspective view of a locking plate.

Referring more particularly to the drawings, 1 indicates the mold walls which are preferably in the form of sheet metal plates. For supporting these walls one or more frames are employed. In this instance, each fname comprises two upright members 2 frames 'to produce having laterally-turned ends 3 at their up perspective view of a Ina-1l per ends secured by bolts 4 to two slide bars 5 and 6, each ot said bars of openings 7 whereby the diii'erent distances apart to adapt the machine to walls of different thicknesses. The bars or slides 5 and 6 are arranged one above the other and are connected by vertical bolts 8 which operate in slots 9 to permit the sliding movement. Movement between the slides may be eifected in any suitable means as,'for instance, by a lever 10 pivoted at l1 to the lower slide bar and having a link 12 pivoted thereto at 13 and to the upper slide bar at 14, thereby forming a toggle which, when broken,v moves the bars in one direction and when straightened moves the bars in the other direction.

The mold walls 1 are mounted on the frame uprights 2 so as to be adjusted longitudinally in order that said plates may be projected diiierent distances from both sides of the frame. Any suitable means may be employed for securing the plates in position, but in this instance the lower ends of the uprights are formed with hooks 15 which are flush with rights and receive the lower edges of the mold walls 1, said edges being deflected outwardly at 16'in order to facilitate the positioning the mold upon acompleted portion ot a wall o1" a building. The upper edge of each mold wall may be held to its upright 2`by a clamping collar 1? which surrounds the upright and has a lip 18 overhanging the wall, a set screw 19 on the collar coperating with the upright to hold' the collar against movement.

In Figs. 4 and 5, two machines are shown connected together for the purpose of building a corner. ln this instance, each machine has one of its wallsl projected at one side of the frame' beyond the other, jected wall abuts the projected wall on the other machine at the same time thatthe other two walls of the machines are brought into abutment. To lock the two walls at the outer edge of the corner of the machine, each of said walls is provided preferably with two alined eyes 20 on its outer face and within these eyes, projections 21 cna connecting or locking member 22 are received, the locking member having two pairs of alined projections, one pair being longer than the other so that one side of the conhaving a plurality for the passage of the bolts 4,

the inner faces of the upand this pro- Y uprights may be positioned at tio vedge of the latter wall.

nection may be attached betere the other. i hand piece 28 is provided on the connec- `on by which the latter may be manipulated. lllit-h the purpose in View of forming an air space in the building wall, constructed :trom the adjustment shown in Figs; d and 5, a core Qi is provided which conforms to the angle ot the corner and preferably has a supporting plate at opposite ends which rest upon seats 26 for ed on one side of two core-supporting members. 27, the latter being secured by bolts 28 to the slide bars and 5, To prevent the cement worling between these supporting members 2T, the latter are provided with overlapping plates which close the space between the members on one side thereof.

ln the adjustment shown in Fig. 6, three molding machines are connected to :form two adjacent corners as well as to hug closely an adjacent window frame. ln this arrangement instead ot the side edges of two mold walls being connected, a side edge of one mold wall is connected to another` mold wall at a. point removed trom the side To permit this connection, each mold wall l may have two horizontal or longitudinally extending series ot openings 30 which are larger at one end than at the other. These openings are adapted to brought opposite the eyes 2O on an adjacent wall in order that alined pintles 3l which are carried by lateral projections 32 on a locking plate 355 may be introducefVv with their projections 32 through the openings 30 to engage within the eyes, the I tions 3Q being enlarged at their t when the narrow portions of tions enter the narrow portions Vs 30, the loch bar will be held -il hold a plate l one end of another plate. the adjustment shown in (i, core member 24# isprovided with supporting plates the latter projecting from one end the core and Laying downwardlyturned portions Qb on opposite sides, in rc the supporting member Q52 may rest upon. two shoulders or seats 26@ :termed by the upper edges-of two plate extensions 27a on supports 27. Between two of the plates l a window frame X is received, a

v core Q4? being interposed between the trame I and the adjacent molding machine Jframe.

At both of the corners formed by this adjustment, two upright angle bars 34C are arranged, said bars being set in a vertical position to dene the position ot the molding machine. as each portion of the wall is built upwardly along the angle bars. lt desired, clamps may secure the plates l to the angle bars. rhis bar 34- may also be used in connection with the adjustment lshown in Fig. 4l.

ln the adjustment shown in llig. 8, two

trames are connected to the walls l,

each frame being connected to both wails near one end of each. i core member 24C with supporting plates 25a having flanges is supported on the seats 26a. lt is apparent that the length of this' core, aswell as the length ot' the plates l, may be Varied to make machines of different lengths. rllhis adjustment is designed for making a straight wall with an air space.

ln using the machine, the two walls l are supported on suitable cross pieces such as sheet metal strips which lie. within the recesses 36 in the lower edges of the plates l. A@fitter the side walls l hare been positioned, the core is introduced in place and supported as described, provided that it is desired to build a wall with an air space. li' a solid wall is to be built, the core supports 2'? are removed. The machine is iilled with the cement which is then tamped, after which the machine is immediately removed trom the wall, the core piece being first withdrawn, when the walls l may be separated by moving the operating lever l0.

'll his invention permits the Jornration of corners from the walls of the molds without the provision of any extensions on said walls. rl`he. walls are longitudinally adjustable on their supporting trames so that they may be projected dil'lierent distances beyond the trame and in this way may form corners ol any angles. This adjustment also permits the machine to hug closely a window or door trame and at the same time the building ot straight walls is possible. Certain features herein shown are broadly in an application filed by 18th day of June, QlG, Ser
